The photocatalytic activity of ZnO nanomaterials for the degradation of some organic pollutants in water [173] (e.g., dyes [174]) was explored by several groups to achieve environmental benefits. Recent studies have indicated that ZnO can be used under acidic or alkaline conditions with the proper treatment [175,176]. ZnO nanomaterials were used as photocatalysts for the degradation of phenol [177] and chlorinated phenols such as 2,4,6-trichlorophenol [178]. ZnO nanomaterials were also used for the degradation of Methylene Blue [179], direct dyes [180], Acid Red [181], and Ethyl Violet [182],...

Polyvinyl chloride (PVC) Ti(OH)4 sol is prepared by adding 20 mL of TiCl4 to 40 mL ethanol (95%) under stirring condition at 0°C. 3.0 g PVC powders is added into the 10 mL of Ti(OH)4 sol and the mixture is stirred for another 72 h. The product is filtered and dried at room temperature. After calcination at appreciate temperature for 0.5 h, ri02/conjugated polymer complex is obtained Photocatalytic degradation of methylene blue [584]...
